→ compared with the concrete structure, the I-steel structure can increase the service area by % reduce the self weight of the structure by % - %, and reduce the structural design internal force.→ wide flange and large lateral stiffness. Strong bending resistance.Buenos Aires,Installing the pipe structure means the complexity of some elements.I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.Wuerden,I-beam is a long strip steel with groove section which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel,Buenos AiresHow much is I-beam per square meter, etc.→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.Defects of alloy pipe and solutions:

The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm. Simple section steel pipe -- circular steel pipe square steel pipe, oval steel pipe,Buenos AiresHow many kilograms per meter of 80 welded pipe, triangular steel pipe, hexagonal steel pipe, rhombic steel pipe, octagonal steel pipe, semi-circular steel pipe, others.Generally, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing,Buenos AiresHow much is I-beam per ton, there is no harm to carry out hot galvanizing in the middle and later stage.Service first, Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, most of the flat steel on the market are finished steel, which can be used ready-made for components, ladders, whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Good quality, The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.Compared with manual binding, welded steel mesh can reduce the occurrence of cracks by more than %. The use of reinforcement mesh can make the project construction faster. As long as the reinforcement mesh is laid as required, the concrete can be poured, eliminating the links of reinforcement on-site cutting, placing one by one and binding. It can save % - % of working hours,Buenos Aires,All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.I-beam, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape. Frame line crack
